Analys av arbetsmiljö vid kokarpåsvetsning samt förslag till förbättringar.
Denna rapport är ett inledande steg mot att förbättra arbetsmiljön för svetsare vid påsvetsning med Uddcomb Metoden i massakokare. Syftet med rapporten är att analysera problemet med värme och dålig luft samt förklara hur och varför problemet uppstår. I arbetet ingår även att ta fram olika lösningar för att slutligen hitta ett komplett system för ventilation och kylning. Den föreslagna lösningen består av ett integrerat kylsystem och ett koncept med mindre fläktar, kallade torpeder, som monteras på arbetsplanen vilka driver ut varm och smutsig luft snabbare ur kokaren. Den föreslagna lösningen utreds även ur ett ekonomiskt perspektiv.
Den som vet bäst vinner mest - Om information i butik och hur den används.
When in the process of buying a product based high effort behavior, the consumer needs information to decide on which product that best satisfies their need. There is a wide arrange of sources where this could be found. One of the most important, due to the great influence it has on consumer choice, is in-store communications. This is also one of the least developed sources. It is not uncommon that the only facts that can be acquired are found on product packaging and from contact with the store´s staff.
Fast driftställe enligt OECD:s modellavtal i ljuset av elektronisk handel
The purpose of this thesis is to examine whether the concept of permanent establishment, as defined in Article 5 of the OECD Model Tax Convention on Income and Capital, is applicable to electronic commerce and if so whether the current definition is able to appropriately deal with the challenges of electronic commerce.In 2003, the OECD added a new section to the Commentary on the Model Tax Convention on Article 5. The new section is a clarification on the application of the permanent establishment definition in electronic commerce.The current definition of permanent establishment in the Model Tax Convention relies on the physical presence of a foreign corporation as the threshold for source taxation. While the current definition, prima facie, might be applicable on electronic commerce, the highly mobile nature of electronic commerce might affect the current revenue distribution equilibrium between states..
Röhsska Backstage : är publika arbetsmetoder nästa steg framåt?
The Röhsska museum in Gothenburg has recently launched a new work method, Backstage, that is studied and paralleled to the museums permanent exhibition on Japanese design. In Backstage the museums routine work is executed in full view of the museums visitors in an exhibition area. The study has focused on the museums intentions and the visitors? interpretations in Backstage and Japanese design, as well as the staff?s experience of the work method?s public aspects. The study?s empirical material has been collected through interviews with the museum staff as well as observations and interviews with visitors in both Backstage and Japanese design.
Europa - en plats eller en idé? : En diskursanalys av den europeiska identitetens konstruktion
Today Europe is faced with an identity crisis concerning its borders. Turkey stands at the threshold for an EU-membership while the EU-Commission is trying to formulate what constitutes a European identity. This identity seeking process will determine the future not only for Turkey, but also for immigrants now living in Europe.In this thesis a discourse analysis, underpinned by socialconstructionist theory, is conducted to explore how the European identity has been constructed throughout history up until today. A starting point is that identity always is defined through a dialectical relationship to "otherness". Therefore the analysis is focused not only on what a European identity consists of but also what and who it excludes.
Vibrationsmätning med mobiltelefon
Vibrationsrelaterade problem tenderar att bli mer och mer uppmärksammade, inte bara inom byggindustrin där många handverktyg används, utan även inom transportväsendet. En fordonsförare som under större delen av sin arbetsdag kör på ibland väldigt ojämna vägar, utsätts för skadliga nivåer som man inte alltid tänker på. Detta examensarbete kommer att behandla utvecklingsprocessen för ett system som kan överföra data från en vibrationsmätare till en mobiltelefon för analys och presentation av mätvärden. Genom att använda sig av detta system kan fordonsföraren lättare hålla koll på vad han utsätter sig för under en arbetsdag. Detta torde leda till en lägre vibrationsexponering bland annat genom en försiktigare körning, något som i slutändan kommer att gynna även eventuella passagerare.
Årets gränsbelopp : Vem kan betraktas som ägare vid årets ingång
Being able to know how use the rules about how taxes works, allows a shareholder with qualified holding in a closely held company, to pay less taxes. When the owner of the share makes an agreement, which the ownership rights transfers later than the actual date for when legal contract is written. The question is therefore who can consider being the new owner at the beginning of the year and taking part of the benefits. Do the ownership rights transfer on the contract date or the date of access?When a buyer purchase a share during the year, he may not partake of any threshold amount, then the expected time is for those who are owners at the beginning of the year.
Investigation of tissue factor mRNA levels in human platelets using real-time PCR
Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.
Ett Radikalt Högerpopulistiskt Parti i Regeringen : En studie av FPÖ och dess valframgång i Österrike 1999
In this research paper I have interpreted and analysed how it is possible for a Radical Right Populist Party such as FPÖ (The Freedom Party) to obtain electoral success in the end of the last millennium. In 1999 they were elected into the national legislative parliament with 26.9% of the votes and participated in the Shüssel government from February 2000. I believe this is an extreme case study and my method is the so called Disciplined-configurative case study. I?ve conducted this study by using earlier published research and than dividing these old theories into to three analytical categories.
Effektiv signalering av kritisk information : sepsisvarning på en akutvårdsavdelning
Denna studie har som syfte att undersöka hur signaler på en akutvårdsavdelning påverkar akutvårdspersonalen idag samt hur en varningssignal för sepsis bör utformas för att passa in i miljön och minska risken för larmtrötthet. I studien har kvalitativa metoder använts i form av observationer på en akutvårdsavdelning samt tre stycken intervjuer. Datamaterialet har sedan analyserats med hjälp av det teoretiska ramverket Distributed Cognition for Teamwork (DiCot). Studien resulterade i en kartläggning över vilka signaler som finns på akutvårdsavdelningen idag, där sepsis skulle klassas som en akut varningssignal och ha högsta prioritet i förhållande till de andra signalerna. Varningssignalen bör i de fall då patienten ligger på ett övervak presenteras så att den når all personal och med säkerhet uppmärksammas. I de fall då vårdlaget befinner sig på platsen när varningen kan uppstå bör larmet istället vara mobilt och enbart presenteras för vårdlaget.
Dem matematiska problemlösningens roll i lärarens undervisning.
The purpose of this paper was to examine how clients on the unit for adults at Södemalms district administration (Stockholm, Sweden) with severe mental illness and substance abuse differs from other clients with substance abuse at the baseline and at follow-up one year later. We have used a quantitative method and analyzed material from ASI-interviews performed at the adult drug abuse unit at Södermalm during the time period 2002-2010. At the baseline the clients with substance abuse and co-occurring severe mental illness have more problems than other clients, primarily in the area of mental health. They spend more time alone and are more likely to engage in illegal activities. Interviewers assess their situation as more serious and that they need more help in all of ASI's areas of life than other clients.
Ovillkorade aktieägartillskott - Analys utifrån skatteflyktslagen
Partner in a close company is taxed under special rules for private companies. This is to avoid a fiscal revenue conversion. Partner as having a major influence in the company and take out what is really earned income as dividends and thus be taxed at a significantly lower rate. The purpose of the close company rules is that a partner in labor income is taxed in the same way that an employee?s income.The problem that arises when one partner in a closely held company leave a shareholders contribution to the company which aims to raise the threshold for the shares discussed in this paper.
Automatisk Identifiering av Inandningspauser i Spontant Tal - ett HMM/ANN-hybridsystem i Matlab
This thesis presents a system which has been implemented to satisfy a need in theresearch on how speech planning interacts with syntactic and prosodic structure inspontaneous speech. The long-term purpose of the research is to provide models forautomatic parsing of spontaneous speech and for psycholinguistical modelling of speechproduction. Identification of inhalation pauses is an important step in the developmentof automatic methods for spontaneous speech parsing.Identification of inhalation pauses is considered to be a keyword-spotting speechrecognition problem. Hybrid HMM(Hidden Markov Models)/ANN(Artificial NeuralNetworks) approach is applied to this problem. Method gets 90,8% in Recall, 66,4% inPrecision and 76,7% in F-score.
Technologised Parenthood: An Ethical Implacation of Human Reproductive Cloning
Science and technology has been the bedrock of human growth and dynamism. Man has over the years distinguished his existence from all other beings by his ability to champion and fashion his existence. Among his tools is biotechnology which actually attenuates the fears of aging and death.Human reproductive cloning stands out as one of the means through which biotechnology plans to achieve this perfect existence for man. Technological advancements in the field of biotechnology are now in the threshold of human procreation.Human reproductive cloning is seen as an assisted method of reproduction which creates a newborn that is genetically identical to another human being.Human reproductive cloning as a technology and as a means of reproduction is not without its pros and cons. In as much as the technology promises to mention but a few, hope for the infertile couples and single parents, as well as the hope of reproduction without passing on hereditary diseases; it at the same time beeps some flashes of worry.
Optimering och validering av PCR-metod för diagnostik av svampinfektioner i nagel
Nuvarande metoder för att diagnostisera svampinfektioner i nagel är långsamma och troligen ganska okänsliga. Diagnostik görs vanligen genom direktmikroskopi och odling på svampsubstrat. I ett försök att minska analystiden och att öka känsligheten användes i denna studie realtids-PCR (Polymerase Chain Reaction) för att påvisa dermatofyter. Optimering och validering gjordes av en PCR som var generell för dermatofyter och en PCR som var specifik för Trichophyton rubrum. Optimeringen innefattade annealingtemperatur, Mg2+-koncentration och primerkoncentration.
